Most of Kentucky's Republican federal delegation asked the four Republican gubernatorial candidates Thursday to promise that they will show unity after the May primary.
In a letter sent to the candidates Thursday morning, U.S. Senate Majority Leader Mitch McConnell; U.S. Sen. Rand Paul; and U.S. Reps. Ed Whitfield, Brett Guthrie, Hal Rogers and Andy Barr asked the four men running to "pledge to join us in a show of unity at the statewide Lincoln Day dinner in Lexington on May 30."
U.S. Rep. Thomas Massie's name is not on the letter, and during last year's U.S. Senate Republican primary, the congressman declined to sign a similar letter.
At the time, McConnell was fending off Louisville businessman and current gubernatorial candidate Matt Bevin, who also declined at the time to sign a letter pledging to support the eventual GOP nominee.
The letter, written on the letterhead of the Republican Party of Kentucky, was sent Thursday. It argued that "all of our Republican candidates have better ideas that will better serve our citizens, and that the competitive GOP primary in which you are currently engaged is a sign of the vitality of our party."
"But once the primary is over, it is essential for all Republicans to unite around our nominees and work together toward victory next fall," the letter stated.
